Certified Tankless Water Heater Repair Services Backed by Experience
Tankless water heaters are a superior, energy-efficient solution for modern homes—but like any advanced system, they sometimes need attention. If you’re experiencing issues with your tankless system, it’s important to call a certified expert in tankless water heater repair. At Aaron Plumbing, our highly trained team is ready to help you restore comfort, efficiency, and reliability.
Tankless Water Heater Benefits
Tankless water heaters are the new standard in hot water because they provide endless hot water on demand, save energy, reduce utility bills, and last significantly longer than traditional tank-style models. Their sleek, wall-mounted design saves space and lowers the risk of leaks. Plus, with proper maintenance, they can last 20 years or more.
Why Homeowners Need Tankless Water Heater Repair Services
Tankless systems are built to last, but problems can still arise—especially when the system wasn’t installed or maintained properly. Our technicians are trained to handle a full range of issues, including:
- Improper installation by unqualified contractors
- Missed or infrequent maintenance
- Mineral buildup from hard water
- Gas supply issues
- Recirculation and flow rate problems
- Error codes and ignition failure
Some of these issues stem from earlier tankless models that weren’t as advanced, or from homes where water filtration hasn’t been installed. Over time, even the best systems may experience wear or buildup that requires professional service.
Complex Systems Require a Certified Tankless Water Heater Plumber
Tankless water heaters aren’t like standard tank systems. They include advanced digital controls, sensors, and complex components. A general plumber may not be equipped to repair a tankless system correctly—and doing it wrong could reduce efficiency, shorten the unit’s lifespan, or void the warranty.
That’s why Aaron Plumbing technicians receive specialized training and certifications directly from leading manufacturers like Rinnai and Navien. Our team knows exactly how to diagnose and repair tankless systems, using factory-recommended parts and processes.
Common Tankless Error Codes & What They Mean
Rinnai Error Code List
- Rinnai Error Code 11: Ignition failure, often due to gas or igniter issues.
- Rinnai Error Code 12: Flame failure. May relate to airflow or gas supply.

Navien Tankless Water Heater Error Codes
- Navien Error Code E003: Ignition failure, often gas or igniter related.

If you see one of these codes or experience inconsistent water temperature, it’s time to call a professional.

When selecting a tankless water heater, choosing reputable brands like Rinnai and Navien is crucial. If you find yourself in need of tankless water heater service and you have a leading brand, you’ll be in good hands. Off brands that are available online can be extremely difficult to find parts for and generally do not offer technical support.

How Much Does Tankless Water Heater Repair Cost?
The cost to repair a tankless water heater varies depending on the issue, brand, and age of the unit. While the price may be more than a typical tank heater fix, it’s absolutely worth hiring a trained expert. A proper repair restores full performance, protects your warranty, and helps you avoid more costly issues down the road.
Protect Your Investment with Regular Maintenance
Routine maintenance is crucial for maintaining optimal performance and longevity of your tankless water heater. Regular check-ups prevent minor issues from becoming costly repairs, keep efficiency at peak levels, and help you avoid unexpected breakdowns. Professional maintenance typically involves cleaning components, inspecting for leaks or corrosion, calibrating temperature settings, and verifying safety functions.
During a tankless maintenance service, your technician will flush your water heater to avoid scale build up. They’ll also check the history of your water heater to see if any error codes have been triggered so that those can be addressed proactively.
With a whole house water filter, you can have your tankless water heater maintenance service performed less often.
